A circle is given by `x^2 + (y-1) ^2 = 1`, another circle C touches it externally and also the x-axis, then the locus of center is:

A circle passes thorugh A(2,1) and touches y-axis then the locus of its centre is

A circle touches x-axis and cuts off constant length 2p from y-axis then the locus of its centre is

A variable circle is drawn to touch the line 3x – 4y = 10 and also the circle x^2 + y^2 = 1 externally then the locus of its centre is -

If C_(1): x^(2)+y^(2) =(3+2sqrt(2))^(2) be a circle. PA and PB are pair of tangents on C_(1) where P is any point on the director circle of C_(1) , then the radius of the smallest circle which touches C_(1) externally and also the two tangents PA and PB is

A circle touches the line L and the circle C_(1) externally such that both the circles are on the same side of the line, then the locus of centre of the circle is :

Locus of the centre of the circle which touches x^2+y^2 - 6x-6y+14 =0 externally and also y-axis is:
